SKATE.

SPECIFICATION part of Letters Patent No. 321,412, dated June 30, 1885.

A pplieatien filed January 3, 1835. (No model.) y

To all whom it 12mg concern:

Be it known that I, @Hannes O. YALE, of Rome, in the county of Oneida, in the State of New York, have invented new and useful Improvements in Roller-Skates, of which the following, taken Yin connection with the aecompanying drawings, is a full, clear, and exact description.

This invention consists in a novel construction and combination of gripping devices connected to the foot-plate of the skate for the purpose of securely fastening the skate to boots or shoes of different sizes, all as hereinafter more fully described, and speeically set forth in the claims.

The invention is fully illustrated in the annexed drawings, wherein Figure l is a side elevation of the rear portion of a skate provided with my invention. Fig. 2 is a top plan view of the saine. Fig. 3 is a vertical transverse section taken on a line m in Fig. 6. Fig. et is a vertical transverse section illustrating the operation of the gripping-jaws in engaging the solo of the boot or shoe. Figs. 5 and 7 are enlarged detail views illustrating the means for retaining the jaws in their engageruent with the sole of the boot or shoe. Fig. 6 is an inverted plan view of the forward end of the footplate and attaching devices connected therewith.

Similar letters of reference indicate corresponding parts.

F represents the foot-plate of the skate. To the under side of the forward portion of said plate I adjustablysecure two plates, B B, provided with transverse slots yr i', through two of which the attachingscrews pass, a clamping-screw, n, passing through another of the slots, and, entering the foot-plate F, serves to retain said plate in its position. The plates B B projectbeyond the side edges of the footplate, and on the projecting portions of the plates B B are hinged the jaws C C, which are arranged to oscillate vertically toward and from the foot-plate- From said jaws project levers ll inwardly and upwardly sufficient to receive the downward pressure of the foot,and by said pressure automatically crowd the jaws C- C into engagement with the edges of the sole of the boot or shoe, as represented in Fig. 4: of the drawings. By placing the fulcrums of the jaws outside of the side edges of the footplate, the jaws are caused to press downward on the sole, and thus obtain a more secure hold thereon.

From the lower or pivoted ends of the jaws C O project inward secondary levers Z', and between the free end of said secondary levers and the plates B B, I employ suitable locking devices-such as keys or wedges a-for the purpose of retaining the jaws in their engagement with the sole of the boot or shoe. By means of springs f, secured to the plates B B and pressing against the ends of the keys or wedges, the latter are automatically forced into their engagement with the levers Z l. The abovedeseribed jaw O and its levers Z and Z, I form in one piece of metal, and thus impart to the respective members the requisite stability.

b b represent the usual lugs attached to the heel of the foot-plate F, for the purpose of engaging the heel of the boot or shoe, said plates being provided with inward projections o c for that purpose. In order to render said lugs adjustable in their position,I provide their base with slots s s for the reception of the screws e e, by which said lugs are clamped on t-he foot-plate, said slots allowing the lugs to be set in or out, according to the size of the heel of the boot or shoe to which the skate is to be fastened.

Between the central portion and heel portion of the foot-plate I adj ustably secure a block, d, by means of a screw, m, passing through a longitudinal slot in the foot-plate and engaging the said block. The rea-r face of the block d is inclined, as shown in Fig. l of the drawings, for the purpose of crowding the heel back against the lugs b b, and thus cause the latter to obtain a firm hold on the heel.

Having described my invention, what I claim isl. The combination, with the foot-plate of a skate, of jaws pivoted at opposite edges of said plate, levers extending inward from said jaws to receive the downward pressure of the foot, keys or wedges for retaining the levers in their depressed position, and springs arranged to automatically force the keys or wedges into their engagement with the levers, substantially as described and shown.

ICO

2. The combination, with the foot-plate of a skate, of plates secured thereon adjustable laterally, jaws pivoted on said plates and arranged to engage the edges of the sole of the boot or shoe, levers extending inward from the jaws to receive the downward pressure of the foot, keys or wedges for retaining the levers in their depressed position, and springs arranged to force the keys or wedges into their engagement with the levers, all combined to operate substantially as set forth and shown.

3. In combination with the foot-plate F and key or wedge ce, the vertically-oscillatory jaw C, pivoted at its lower end, and the inwardprojecting lever Z and secondary lever Z, both formed integral with the jaw, substantially as described and shown.

et. In combination with the foot-plate F, the plates B B, adjustably connected to the footplate and projecting beyond the side edges thereof, the jaws C C, pivoted on the projecting portions of the plate B B, and provided with the inward-projecting upper levers, Z Z, and with the supplemental lower levers, Z Z',

and the keys a a, entering between the plates B B and levers Z Z', substantially as described and shown.

5. In combination with the foot-plate F, the plates B B, adj ustably connected to said footplate and projecting beyond the 'side edges thereof', the jaws C C, pivoted on the projecting portions of the plates B B, and provided with the inward-projecting upper levers, ZZ, and the supplemental lower levers, Z Z, the keys a a, entering between the plates B B and levers Z Z', and the springs f f, pressing the said keys into their said engagement, substantially as described and shown.

In testimony whereof I have hereunto signed my name and afxed my seal, in the presence of two attesting witnesses, at Syracuse, in the county of Onondaga, in the State of New York, this 29th day of December, 1884.
